SALEM, ORE. — Diamond Foods is celebrating the 30th anniversary of the launch of its Kettle Brand with the reintroduction of four of its most popular varieties: Red Chili, Jalapeño Jack, Salsa with Mesquite and Cheddar Beer.

“Reflecting on 30 years was a great reminder of how flavor innovation is so rooted in everything we do,” said Carolyn Ottenheimer, chief flavor architect. “It was easy to spot how we’ve often been ahead of our time, on the cusp of culinary trends that are just starting to hit American culture.”

• Red Chili — Introduced in 1982, the first flavor produced after the original Unsalted and Lightly Salted mirrors the taste of sriracha sauce combined with a vinegar tang. Cayenne pepper is used for a searing red chili heat.

• Jalapeño Jack — The second-oldest retired flavor in the collection that debuted in 1989 has a creamy, salty Jack cheese base mixed with the spice of red and green peppers, and a strong jalapeño flavor.

• Salsa with Mesquite — Launched in 1999, this variety combines salsa with mesquite barbeque. Tomatoes, bell peppers, onions and garlic blend with lime to create a flavor combination that’s sweet, smoky and salty.

• Cheddar Beer — This chip debuted as a fan pick during the brand’s first People’s Choice vote in 2005. It combines tangy sharp cheese with malty beer notes.

The flavors will be introduced in 5-oz bags retailing for $2.79 in natural grocery stores this summer, and distribution will be offered to mainstream food retailers in 8.5-oz bags retailing for $3.49 in the fall. The collection is also available on-line at www.kettlebrand.com beginning in July.
